Before you touch a single screw or wire, it’s important to prepare. Rushing into installation without the right tools or knowledge can lead to frustration—or worse, electrical hazards. Here’s everything you’ll need to install your Google Nest Doorbell (2nd Gen).
1. Choose Your Model
First, confirm which version of the Nest Doorbell (2nd Gen) you have:
– Battery model: Runs on a built-in rechargeable battery. Ideal if you don’t have existing doorbell wiring or prefer a wireless setup.
– Wired model: Connects to your home’s low-voltage doorbell wiring (typically 16–24V AC). Offers continuous power without recharging.
If you’re unsure, check the packaging or product listing. The battery model is usually labeled as “Nest Doorbell (battery)” while the wired version is “Nest Doorbell (wired).”
2. Gather Your Tools
Here’s a list of tools you’ll likely need:
– Phillips-head screwdriver
– Drill with a 1/4-inch drill bit (for mounting holes)
– Level (to ensure the doorbell is straight)
– Pencil (for marking drill points)
– Smartphone or tablet with the Google Home app installed
– Ladder (if your doorbell is high up)
– Optional: Voltage tester (for wired installations)
For wired installations, you may also need wire strippers if your existing wires are frayed or too short.
3. Check Compatibility (Wired Model Only)
If you’re installing the wired version, your existing doorbell system must meet Google’s requirements:
– Voltage: 16–24V AC
– Transformer: Must be compatible with smart doorbells (most modern homes are fine)
– Chime: Mechanical or digital chimes are supported, but some older models may require a Nest Chime Connector (sold separately)
To check your voltage:
1. Turn off power at the breaker.
2. Remove your old doorbell.
3. Use a multimeter or voltage tester to measure the voltage across the two wires.
4. If it reads between 16 and 24 volts AC, you’re good to go.
If your voltage is too low or too high, consult an electrician before proceeding.
4. Download the Google Home App
The Google Home app is essential for setup, configuration, and managing your Nest Doorbell. It’s available for free on:
– iOS (iPhone/iPad) via the App Store
– Android via Google Play
Make sure your phone is connected to your home Wi-Fi network (2.4 GHz or 5 GHz). The app will guide you through the entire setup process, including connecting to Wi-Fi, naming your doorbell, and adjusting settings.
Step 1: Turn Off Power (Wired Model Only)
Safety first! If you’re installing the wired Nest Doorbell, you must turn off power to avoid electric shock.
How to Safely Turn Off Power
1. Locate your home’s electrical panel (breaker box).
2. Find the circuit that controls your doorbell. It’s often labeled “Doorbell,” “Chime,” or “HVAC.” If unsure, turn off the main breaker to be safe.
3. Use a non-contact voltage tester at the doorbell location to confirm power is off.
4. Once confirmed, proceed with removing the old doorbell.
⚠️ Never work on live wires. If you’re uncomfortable with electrical work, hire a licensed electrician.
Step 2: Remove Your Old Doorbell
Whether you’re replacing an old mechanical doorbell or upgrading from a previous smart model, you’ll need to remove it first.
For Wired Doorbells
1. Unscrew the front cover of your existing doorbell.
2. Carefully disconnect the two wires from the terminals. Note which wire goes where (usually marked “Front” and “Trans”), but most Nest Doorbells are polarity-insensitive.
3. Remove the mounting plate and set it aside.
For Battery-Powered or Wireless Doorbells
1. Unscrew or unclip the old doorbell from the wall.
2. Remove any mounting brackets or adhesives.
Tip: Take a photo of the wiring before disconnecting anything. This can help if you need to troubleshoot later.
Step 3: Install the Mounting Plate
The Nest Doorbell comes with a mounting plate that secures the device to your wall. Proper alignment is key for both function and aesthetics.
Position the Mounting Plate
1. Hold the mounting plate against the wall where you want to install the doorbell.
2. Use a level to ensure it’s straight.
3. Mark the screw holes with a pencil.
Ideal height: 48 inches (4 feet) from the ground. This ensures clear video of visitors and packages.
Drill and Secure the Plate
1. Drill pilot holes at the marked spots.
2. If mounting into brick, concrete, or tile, use wall anchors.
3. Screw the mounting plate into place using the included screws.
For angled walls or unique setups, Google offers optional wedge mounts (sold separately) to adjust the viewing angle.
Step 4: Connect the Wires (Wired Model Only)
Now it’s time to connect your Nest Doorbell to your home’s wiring.
Prepare the Wires
1. Strip about 1/4 inch of insulation from each wire if needed.
2. Ensure the wires are long enough to reach the terminals on the back of the doorbell.
Attach the Wires
1. Loosen the terminal screws on the back of the Nest Doorbell.
2. Insert each wire into the corresponding terminal (Front and Trans).
3. Tighten the screws to secure the wires.
No need to worry about polarity—the Nest Doorbell works regardless of which wire goes where.
Optional: Use the Nest Chime Connector
If your existing chime doesn’t work with the Nest Doorbell (common with older mechanical chimes), you’ll need the Nest Chime Connector. This small device connects to your chime and ensures it rings when the doorbell is pressed.
Installation steps:
1. Turn off power.
2. Open your chime box.
3. Connect the Chime Connector to the chime terminals.
4. Follow the in-app setup instructions.
Step 5: Attach the Nest Doorbell
With the mounting plate secure and wires connected (if applicable), it’s time to attach the doorbell.
For Wired Models
1. Align the doorbell with the mounting plate.
2. Slide it down until it clicks into place.
3. Secure it with the included security screw using a screwdriver.
For Battery Models
1. Insert the rechargeable battery into the doorbell (if not pre-installed).
2. Align the doorbell with the mounting plate.
3. Slide it down and secure with the security screw.
The battery model doesn’t require wiring, so this step is much simpler.
Step 6: Turn Power Back On (Wired Model Only)
If you turned off the breaker earlier, now’s the time to restore power.
1. Go back to your electrical panel.
2. Turn the doorbell circuit back on.
3. Wait a few seconds for the system to power up.
You should see a light on the front of the doorbell indicating it’s receiving power.
Step 7: Set Up the Doorbell Using the Google Home App
Now that the hardware is installed, it’s time to configure your Nest Doorbell through the Google Home app.
Open the Google Home App
1. Launch the app on your smartphone or tablet.
2. Tap the “+” icon in the top-left corner.
3. Select “Set up device.”
4. Choose “New device.”
Follow the On-Screen Instructions
The app will guide you through:
– Scanning the QR code on the back of the doorbell
– Connecting to your Wi-Fi network (2.4 GHz recommended for better range)
– Naming your doorbell (e.g., “Front Door”)
– Setting up motion zones and alerts
– Testing the doorbell and chime
Tip: Choose a strong Wi-Fi password and ensure your router is within range. Poor signal can cause delays or failed recordings.
Test the Doorbell
1. Press the button on the front of the doorbell.
2. Check that your phone receives a notification.
3. Verify that your chime rings (if wired).
4. Open the live feed in the app to confirm video and audio quality.
Step 8: Adjust Settings and Preferences
Once installed, customize your Nest Doorbell to suit your lifestyle.
Motion and Sound Detection
In the Google Home app:
– Set sensitivity levels for people, packages, and animals.
– Create activity zones to focus on specific areas (e.g., your driveway but not the sidewalk).
Notifications
Choose when and how you’re alerted:
– Immediate alerts for all motion
– Only when someone rings the doorbell
– Scheduled quiet hours (e.g., no alerts after 10 PM)
Video Quality and Storage
The Nest Doorbell records in 1080p HD. Video is stored in the cloud with a Google Nest Aware subscription (optional). Without a subscription, you’ll get 3 hours of event history.
Consider subscribing for:
– 24/7 video history
– Intelligent alerts (e.g., “Person seen”)
– Familiar face detection
Step 9: Maintain Your Nest Doorbell
To keep your doorbell working smoothly, follow these maintenance tips.
Battery Model: Recharge Regularly
– The battery lasts about 1–2 months depending on usage.
– When the app shows low battery, remove the doorbell and charge it via USB-C.
– Reattach once fully charged.
Clean the Lens and Sensor
– Wipe the camera lens and motion sensor with a soft, dry cloth monthly.
– Avoid harsh chemicals or water sprays.
Check Wi-Fi Signal
– Use the Google Home app to check signal strength.
– If weak, consider a Wi-Fi extender or moving your router.
